To all whom it iii/t concern:

13c known that we, J OHN T. SIMPSON and MARSHALL N. Snonnsn'ce, citizensof the United States, residing at Newark, in the county cfiissex tFltate or" New Jersey, have invented c" w and useful EYEZPIOVG- meritsin Lireproot buildings, of which the following is a specification, suchwill onahle those skilled in the art to which it appertains to make anduse the same.

Our invention relates to the construction of fireproof walls,partitions, and the like composed of concrete and reinforcing elementsof metal, the essential points thereof being to provide a Wallconstruction in which shall be employed the minimum amount of oothconcrete metal to produce the desired strength and fireproof qualitiesand in which t e use i'curdaticns required to support cry masonry wallscan be omitted and an economical, strong, fireproof, and seltsupportingconstruction substituted in which all the metal parts used arethoroughly embedded in and 1-, *otecied by the concrete or f plastic"lerials.

or object of our invention is to provide a pie and economical means offormwalls in imitation of stonework and in "which the usual centeringcan be disposed of entirely by forming the walls of clocks made in thedesired shapes in molds and setting the blocks in place after they havebecome hardened.

The invention is lolly disclosed in the following specilicai l, of whichthe accompa nyiug drawings itrm a part, in which the separate parts ofour improvement are desigcated by suitable reference characters in eachof the views, and in which Figure l is an elevation of a portion of awall construction, showing the finished exterior surface, withreinforcing metal members shown by dotted lines. Fig. 2 is a vertical onof the-construction, taken on line 2 2 i 1. 3 is a horizontal section.of the iccnstructicn, taken on the line 3 3 of Fig. rig. 4.- is a planView of the top edge of locks forming the wall construction and mngthegroove for an anchor to attach he blocks to the tension-bars. Fig. 5 isan enlarged elevation of the blocks, showing the reinforcing metal andmeans of connecting the blocks to the metal tension-bars. Figs. 6 and 7are vertical sections of the blocks shown in'Fig. 5 and show the methodof attaching the reinforcing-rods to the metal tensionbars. Fig. 8 is anenlarged section of the metal column, taken on line 8 8 of Fig. Landshows the method of attaching the metal tensiowbars to the column, alsothe manner of embedding and protecting the metal column. Fig. 9 is anenlarged vertical section of Fig. 1, taken on line 9 9 and showing themethod of forming lintels and window-heads. Fig. 10 is an enlargedhorizontal section of Fig. 1, taken on line 10 l0 and showing the methodof attaching the metal tension-bars to the metal framing atwindow-openings. Fig. 11 and Fig. 13 are enlarged partial verticalsections of Fig. 5 and show another method of attaching the blocks tothe metal tension-bars. Fig. 12 is an enlarged Vertical section of Fig.1, taken on line 12 12 and showing the method of attaching the blocks tothe metal frame of the window-sill.

Referring to the drawings, A represents the supporting-piers, upon whichthe metal columns B of the building construction rest in the usualmanner and upon which are placed the reinforced concrete girders C,spanning from pier to pier and forming a water-table base and supportfor the blocks D of the wall construction. These girders C are composedof concrete reinforced with metal bars 2,

which bars pass from end to end and are embedded in the lower-side 0fthe concrete forming the bulk of the girders, together with metalhinders 3, spaced at certain distances apart in the length of girders Cand having one end bentinto the form of a hook a, which passes over themetal tension-bars 4 of the wall construction and is attached thereto.

Between the upright columns B are placed the metal tension-bars 4, whichin the preferred .form are round bars, but may be square, flat, I, L, orT shaped rods or a pair of wires twisted together. These rods 4 areattached to the columns B in some suitable manner and are spaced atcertain distances apart sud run parallel with the girders-C: Upon thesupporting-girders C and between the metal tension-bars 4 arc'placed theconcreteor similar blocks D, having grooves C? so arranged in their topand bottom edges that when they are set out in place the resintension-bars {it will act in tension and the conter being designed to doaway with the usual furring of walls. The outside surface of the blocksD may be finished in any imitations,

of stonework and colored as desired. in the blocks D are embeddeddiagonally placed reinforcing -rods, 5, having their upper ends bentinto the form of a. hook, as shown at a, Fig. 2, 6, 7, and 12, whichhooks a pass over the bars 4 and secure the blocks D in place. Whenthese blocks D are made very thin, an

additional binding material 6, consisting of a. metal fabric, is placeddirectly against the diagonal reinforcing rods 5. Where the blocks canbe made thick, is separate anchor of metal '7 may be used in place ofthe hook at of the reinforcing-rod 5, as shown in Figs. 11 and 13. Ahole bis provided in the blocks 1) to receive these anchors, which areset in a cement joint 8. The blocks D are formed in a. wood or metalmold, and the concrete forming the outside or finished surface of theblocks being pieced in the forms first make it possibie to use atvery'thin cost, and upon this facing cost is then placed the concreteforming the bulk of the blocks and in which are embedded thereinforcing-rods fiend metal fabric 6 as the blocks are formed. Afinished surface can be put on the inner. side of the blocks, ifdesired, in the-seine Way.

The blocks E, forming the pilssters end column protection on the face ofthe well, are formed similar to blocks D and attached to the bars i inthe sense manner.

The interior protection of the columns B may he made of blocks similerto oloclrs l) or formed, as shown, by casting solid concrete F aboutse'me,thoroughly embedding all motel parts in this material. The door orWindori sill G can he formed similar tchlocks D and vanchored tc'thetension-bars i by means of hook-bolts 8, as shown in Fig. 12. The onesings for doors and windows have a metal frame H, made of angles or othersnitehie shapes and having holes to receive the main tension-bars 4,Fig. 10, or anchor-bolts 8 ig,

. 12. The blocks D, sills G, and lintels 3 here edges formed to fitagainst these frames Provision is made to secure the nailing-shins 'weclaim asnew,

'piers, concrete blocks reinforced centre K and to provide means ofattaching the Window or door frames M.

When it is desirable to use thewsll constrnction for more than one storyin height,the

supporting-girders C can be regestedat each floor-level, or the usualsteel-girders used in skelton constructions may he need in their placeto support the weight of the construe-- tion.

Having fully described our invention, what and desire to secure. byLettersPstent, is'-- 1. In a. building construction, piers errsnged atintervals, girders formed of char crete reinforced with steel endresting on and resting on scid girders, end herizontel metaltension-hers placed horizontally and in the joints between the saidblocks, seid gird ers and blocks being also provided with newticnllyarranged binders, substantially as shown end described.

2. The combination in s well or partition construction, of concreteos'similer plastic with steel materials formed into blocks andreinforced with metah girders formed. of concrete rcin forced withmetslrods in the lower side thereof to take the tension stress and whereinthe concrete takes the compressive stress, hinders which pass under themotel tension-rods end no to the upper edge of the girders where one endis sent into the form of a, hook which passes over is main tension-heroi the Well construction anchors the her firmly to the girders,tension-hers pressing oer tween and sttsched to upright celninns whichbars are spsced st certain dislsnees apart and psrsllei to the escewing-girder, moose formed of concrete her ing e groove in the topsnd"notion: edges to receive the resin tension-hers at groove in the end toreceive 1 .5 cement in which the hiccss are set, meiei reinforcingprodshent st the tossed into term of e hook which passes over and secures theblocks to the main tension-lcsre, and e reinforcing motel ichric e..--bedded in said clocks to sfiford additional strength, snhstsntielly asshown. and de-' scribed.
